# OSPFv3

Monitors status of OSPFv3 enabled devices

**Note**: on Cisco devices (IOS/IOS-XE) this checks will only work with default VRF and one OSPFv3 process.\
Also there can be only one address family in the OSPFv3 process. Anything else nedds SNMPv3 contexts.

**Note: see the [Wiki](https://thl-cmk.hopto.org/gitlab/checkmk/vendor-independent/ospfv3/-/wikis/home) for a sample IOS OSPFv3 configuration**

Collection of OSPFv3 checks
*  *ospfv3_general*: monitors the OSPFv3 overall status
*  *ospfv3_area*: monitors OSPFv3 areas
*  *ospfv3_interface*: monitors OSPFv3 enabled interfaces
*  *ospfv3_neighbor*:  monitors OSPFv3 neighbors (IPv6 only)
*  *ospfv3_virtuallink*: monitors OSPFv3 virtual links (IPv6 only)
